Summary
This private earth dam stands at a height of 20 feet and has a maximum storage capacity of 312 acre-feet, providing essential water resources for the community. With a primary purpose of water supply, Sims Dam plays a critical role in managing water resources in the area.
Despite its age, Sims Dam has not been rated for its condition assessment, and its hazard potential is listed as "Not Available." However, the risk assessment categorizes it as having a high risk level of 2, highlighting the importance of monitoring and managing the structure to ensure its continued safety and functionality. While the dam does not have a spillway, it is equipped with one outlet gate, indicating some level of control over water flow.
The Fort Worth District of the US Army Corps of Engineers oversees Sims Dam, with no federal agency funding, design, or construction associated with the structure. As water resource and climate enthusiasts, understanding the importance of maintaining and assessing dams like Sims Dam is crucial for ensuring the sustainable management of water resources and the protection of communities that rely on them for their water supply needs.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
